Westley's early career activities included performing in stock theater and in vaudeville around the United States. Her New York stage debut came on September 13, 1897, when she portrayed Angelina McKeagey in The Captain of the Nonesuch.[2]
Westley married John Westley, a Broadway actor, on October 31, 1900. The couple separated in 1912, with the marriage ending in divorce. The couple had one daughter, Ethel.[3][4]
Westley retired from acting in 1942, and subsequently lived with Ethel at her daughter's home in Middlebush, New Jersey, until Westley's death from an undisclosed illness on December 12, 1942.[1] She was cremated at the Rose Hill Cemetery in Linden, New Jersey. On December 17 of the same year, Ethel had her mother's ashes buried at Cypress Hills Cemetery in Brooklyn, New York, in Section 9, Lot 26 (the same site where Westley's mother and father were buried).[1]
